Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed July 17, 1908. Serial No. 443,980.

To cllwhom it may concern:

Re it known that I, RALPH S. BARRETT, a citizen of 'the United States, residing at Indianapolis, yin the county ofMarion and State of Indiana, have invented certain new and useful Improvements in Adjustable- Wrench Handles; and I do declare the following to be a full, clear, and exactdescription of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference markedthereon, which form a part of this specification.

This invention relates to the well known type of wrenches commonly named monkey wrench, and has reference particularly to built-up handles thereof, and especiallyT to the external portions of the handles.

The object of. the invention primarily is to provide improved handle Iframes that will be adapted to be formed of cast metal such as steel or malleable-iron in a cheap manner; a further object being to provide an iinproved handle frame that will be adapted to have simple and cheap forms of wooden or other filling pieces connected thereto, a still further object being to provide improvements in wrench handles whereby they may be made inexpensively, and be very strong and convenient to handle, and durable in use', and adapted to prevent in a great measure injury to the filling pieces when the wrenches are placed on work benches or floors, or elsewhere.

With the above mentioned and other obconsists in an improved wrench handle having certain novel features of construction, and consisting further in the parts, and combinations and arrangements'of parts, as hereinafter particularly described and defined in the accompanying claims.

Referring to the drawings, Figure 1 is a front view of a quick acting adjustable wrench having the improved handle thereon,

the wrench being shown as when placed on a plane surface, as a bench, with the undermost portions of the handle filling piece heldl clear of the plane surface, so that the wooden portion may not bc marred by contact with the work-bench or metal chippin'gs that might be on the bench; Fig. 2, a longitudinal sectional view on the line A-A' in Fig. 1; Fig.v 3, alongitudinal sectional view of the handle on the line B in Fig. 2; Fig. 4, a side elevation of the handle; Fig. 5. a

transverse sectional view on the line O-O in Fig. 2; Fig. 6, a side elevation of the handle frame; Fig. 7, a transverse sectional view on the line DWD in Fig. 4; Fig. S, a transverse sectional view on the line E-E in Fig. 6; Fig. 9, a transverse sectional view on the line F-F in Fig. 4; Fig. 10, a longitudinal sectional view on the line G-G in Fig. 6; Fig. 11, a plan of the inner side of either one of the filling pieces of the handle; and Fig. 12, a perspective view of the handle frame. H-H indicates the plane on which thc wrench will normally lie when placed on its side.

Similar reference characters throughout the drawings indicate corresponding elements or features of construction referred to herein.

In the drawings the numeral 1 indicates the body part forming a part of a lever and having a fixed jaw 2 on one end thereof, a movable jaw 3 being mounted slidingly on the body part and having an extension 4 formed therewith in which are screw-threads 5, all formed in the usual manner, the body art having a shallow groove 6 in a side thereof that is adjacent to the extension. The handle is formed partially by the portion 7 of the body-part which has two tapering portions 8 and 8 from which extends a relatively thin shank 9 also forming a part of the lever and the handle, the shank being of the same width as the body part and having beveled sides 10 and 10 at the end portion 9 of the shank, the end 9 of the shank being squared.

The principal part of the improved handle is cast in a single piece, preferably of steel, and constitutes a fraine'having a collar 11 in which is an opening 11 to receive the handle portion 7, two oppositc'sides of the collar having rivet holes 12 and llgtlicrein receiving a rivet 13 that extends through the liandle portion 7 on which the collar is rigidly secured by the rivet, the collar serving 'to strengthen the handle portion 7. has an abutment 14 formed on one side thereof in which screw-threads 15 are formed. A double ended screw is provided having continuous threads 16 on one end thereof engaging the threads 15 and oppositely pitched threads 17 engaging the threads 5 in the extension 4 of the movable jaw, the screw having an enlargement at lthe middle. of its length formed as aknurled turning wheel '18 The collar Y that is toward the jaws of the wrench to serve as sup orts for holding the handle of the wrench diear of any surface u on\which the wrench may be placed on' eit er one of two of its sides, there being also a reinforcing fiange 21 on the end of the collar and joined to the flanges 2O and 20. Two bars 22 and 23 extend from the end 24 of the collar 11 along the op osite narrower sides of the shank part 9, t e inner sides 22 and 23 being straight and parallel one to the other and in the planes of the narrower sides of the oblong aperture 11. 4Thehend 24 has a square face and the bars 22 and 23 have relatively broad portions where they join the collar 11 that 25 ave inclined sides 25 and 25. A cap 26 is formed on the ends of the bars and has two grooves formed -in opposite sides thereof havf ing bottoms 27 and 27' that extend from the planes of the inner sides of the bars con- 3o vergently to the inner side of the end of the cap, the cap having a squared inner end 28 that is parallel to the squared face 24 of the collar, and the other two sides of the cap have internal recesses 29 and 29 so. as to sim- A plify the work of fitting the cap to the end portion 9 of the shank, the grooves receiving f the ta ering sides 10 and 10 thereof, the inner sid; of said cap at the sides ofthe grooves having Walls 30 and 30 and 31 and 31 that engage the broader sides ofthe end portion 9 adjacent to the tapering sides 10 and 10. This construction enables the cap and the shank portion to be readily 'fitted together closely so that rigid connections may be formed tojwithstand the shocks incident to rough handling of the wrench when throwing it about during use. sions 32 and 32 extending from the inner end 28 along opposite sides of the bar 22 and also two other extensions 33 and 33 extend-` ing from the end 28 along opposite sides off The extensions 32 and 33 have the bar 23. divergent inner sides 34 and 34 res -ectively that are straight and stand up at rig t angles to the side facesv of the bars 22 and 23, said extensions projecting inward beyond the inner sides 22 vand 23 of the bars at their bases or junctions with the cap. The other two extensions 32 and 33 have also divergent inner sides 35 and 35 corresponding to those above described. y

In order to fill out the handle to makeit convenient for gras ing in the hand and of a suitable size, two iililing pieces 36 andy 36 are '65 provided of simplified form, so that they may The cap has two exten' be cheaply fitted and made of either wood,

vulcanized fiber, or other suitable material, and are both alike, each filling piece having a squared end 37 that engages the end 24 'of the collar 1l and rests on one/side of the shank portion 9 of the handle, the inner side of the filling piece being iiat and having recesses 38 and 38 to receive the inclined arts 25 and 25 of the bars 22 and 23, the ling piece having an opposite squared end 39 engaging the end 28 of the cap and having also two tapering sides 40 and 40 that engage the inner sides of two extensions of the cap, so that the filling pieces rest on opposite sides of the shank portion 9 and also on the sides of the bars 22 and 23 and are revented from all sliding movements, each ing piece having a rivet hole 41 in its middle portion receiving a rivet 42 that extends v'through the shank portion 9 and secures both filling pieces to their companion parts.,

The wrench is used in the usual manner and when falling or when drop 'ed onto benchesvor floors, will iirst strike t e bench or floor and as usual the wrenchniay then fall on one of its broader sides'which ordinaril hand e, but in the improved wrench the hanwould mar the filling pieces of thedle may be stopped by the flanges 2() and 20',

and thus avoid injury to the more delicate substance of which the iilling pieces are formed. As will he seen also the whole Wrench handle is of compact and rigid construction so that no arts of the frame can yield when in use, an in the'case of accident sufficiently violent to break the handle frame a new frame and frame ieces may be readily substituted for those t at may have been damaged.

Having thus described the invention, what is claime as new, isj 1. A wrench handle frame comprisin a collar and two bars extendin from the oo lar and having a cap formed on t e ends thereof, fsaid ca having two grooves in the inner side gthereo the bottoms ofthe grooves begin- ,l ning at the planes of the inner sides of the bars and extending convergently to the inner side of the end of the cap.

2. A wrench handle frame comprising a collar, and two bars extendin from the'co ar and having a cap formed on t e ends thereof,v
